The element with the lowest average Atomic Mass is hydrogen (H) at 1.008 grams. The element with the highest is meitnerium (Mt) at 266 grams.
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri invented a periodic table in 1869 where he arranged the elements in order of increasing atomic masses.
Most atomic masses on the periodic table are decimal numbers because they are weighted averages of the masses of all isotopes of an element, taking into account their relative abundance. Since isotopes have different masses, the atomic mass is typically not a whole number.
Mendeleev's table was arranged according to increasing atomic masses , which had certain drawbacks. Now, modern periodic table is arranged in order of increasing atomic number.
Properties of elements are a periodic function of their atomic masses.
No. The atomic weight is the number on the Periodic Table and is a weighted average of the atomic masses.
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses. This law changed with the discovery of atomic number by Moseley which stated that the properties of elements are a periodic function of their atomic numbers, leading to a more accurate and modern periodic table based on atomic number.
Each element has its own atomic mass.

Mendeleev discovered old periodic table. He arranged elements in order of atomic masses.
Because the masses of protons, neutrons and electrons are not whole numbers.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
